4 Channel Ignition Coil Driver by AEM Electronics AEMs Ignition Coil Drivers are designed for driving high-power, dwell-controlled ignition coils commonly found on performance engines. Our Three- and Four-Channel versions can be used as a replacement for a stock coil driver or when converting to coil on plug in engines that do not need the extra spark energy from a CDI, or do not have the mounting space for a CDI like on ATVs, snowmobiles, motorcycles and other Powersports applications. Swapping to a coil on plug can eliminate dwell time issues that can be problematic in stock ignition systems, and AEM’s Ignition Coil Drivers are the most affordable way to drive coils in a coil on plug set-up. Features Drive ignition coils on a coil-on-plug set-up without a CDI Three- and Four-Channel Ignition Coil Drivers are ideal for ATV’s, motorcycles, snowmobiles and racing vehicles with space limitations or those that do not require additional voltage generated by a CDI The most affordable, reliable way to drive coils on a COP set up Simple installation Complete hardware included Applications Universal What’s In The Box? 1 – 4 Channel Coil Driver Necessary Hardware References Installation Instructions Warranty Manufacturer Standard Warranty
